Description:
Xia Yi mainly produces shock absorber pistons, industrial pistons with many different dimensions. Piston is
based on powder metallurgy, filled modified PTFE material, using a special way to combine them together,
which has dual advantage of powder metallurgy and PTFE.
We have a strong technical team to develop automatic skirting machines which can assure the
consistency of the pistons and also can improve the work efficiency. Compared with other suppliers, we
are sure we can offer you the best competitive price. At the same time, we have a whole set of testing
machine in our company to test the banding material.
(1)Advantage of powder metallurgy:
Unique chemical composition and mechanical physical properties
(2)Advantage of PTFE:
Chemical and aging resistance, temperature endurance and no-sticky performance
(3)Advantage of piston:
High carrying capacity, good wear resistance, low friction coefficient, good seal and so on
unique hole design lateral force 800N added after piston is in closed in dampers, amplitude +/-25mm
piston ring don't drop down and no abnormal abrasion after 40,000,000 times vibration
Applications:
Car or motorbike shock absorbers
Competitive Advantage:
Proper fillers can reach good seal and friction
Tooling designed by XIAYI can assure the delivery date
A whole set of testing equipment
